> Criminals by definition don't need to follow the law and they don't need the 2nd amendment.

This is kind of an argument from tautology that is disconnected to reality. In the real world, supply of criminality and violence is elastic, if you raise the cost, you lower the amount supplied. Crimes and violence committed are affected by committers having the opportunity and tenacity to do so. If you erect more barriers to achieving it, make it less convenient or straight forward to do it, you'll deter some percentage of violence/criminality who just give up or don't make it past the hurdle or whatever.

Otherwise, to take your argument to its logical conclusion, we could get a whole bunch of dumb conclusions, like:

We should just abolish auditing and other anti-corruption accountability mechanisms. By definition, cheats don't need to follow the law, so auditing doesn't catch them, it just imposes extra paperwork on law-abiding citizens!
